Rename from _Py_INTERNAL_ABI_SLOT to _Py_ABI_SLOT
and define the macro using _PyABIInfo_DEFAULT.
Use the ABI slot in stdlib extension modules to enable running
a check of ABI version compatibility.
_tkinter, _tracemalloc and readline don't use the slots, hence they need
explicit handling.

Use critical sections to make heapq methods that update the heap thread-safe when the GIL is disabled.
---------
Co-authored-by: mpage <mpage@meta.com>
As reported in #117847 and #115366, an unpaired backtick in a docstring
tends to confuse e.g. Sphinx running on subclasses of standard library
objects, and the typographic style of using a backtick as an opening
quote is no longer in favor. Convert almost all uses of the form
The variable `foo' should do xyz
to
The variable 'foo' should do xyz
and also fix up miscellaneous other unpaired backticks (extraneous /
missing characters).
No functional change is intended here other than in human-readable
docstrings.
This PR adds the ability to enable the GIL if it was disabled at
interpreter startup, and modifies the multi-phase module initialization
path to enable the GIL when loading a module, unless that module's spec
includes a slot indicating it can run safely without the GIL.
PEP 703 called the constant for the slot `Py_mod_gil_not_used`; I went
with `Py_MOD_GIL_NOT_USED` for consistency with gh-104148.
A warning will be issued up to once per interpreter for the first
GIL-using module that is loaded. If `-v` is given, a shorter message
will be printed to stderr every time a GIL-using module is loaded
(including the first one that issues a warning).
Here we are doing no more than adding the value for Py_mod_multiple_interpreters and using it for stdlib modules. We will start checking for it in gh-104206 (once PyInterpreterState.ceval.own_gil is added in gh-104204).
setup.py no longer defines Py_BUILD_CORE_MODULE. Instead every
module defines the macro before #include "Python.h" unless
Py_BUILD_CORE_BUILTIN is already defined.
Py_BUILD_CORE_BUILTIN is defined for every module that is built by
Modules/Setup.
The PR also simplifies Modules/Setup. Makefile and makesetup
already define Py_BUILD_CORE_BUILTIN and include Modules/internal
for us.

Replaces the PyList_GET_ITEM and PyList_SET_ITEM macros with normal array
accesses. Replace the siftup unpredicatable branch with arithmetic.
Replace the rc == -1 tests with rc < 0. Gives nicer looking assembly
with both Clang and GCC-4.9. Also gives a small performance both for both.
Clean-up names of static functions.
Use Py_RETURN_NONE macro.
Expose private functions needed to support merge().
Move C imports to the bottom of the Python file.
Consolidates the logic for nlargest() into a single function so that
decoration tuples (elem,order) or (key, order, elem) only need to
be formed when a new element is added to the heap. Formerly, a tuple
was created for every element regardless of whether it was added to
the heap.
The change reduces the number of tuples created, the number of ordering
integers created, and total number of tuple comparisons.
now heapqueue items must implement the "<" operator.
The compatibility code could not work: all 3.0 objects have a __lt__ method
(which returns NotImplemented)
Twisted will have to adapt its DelayedCall class.
